Good luck finding a Made in USA/UK computer.
Even assembled in these countries from Taiwan/China parts would rise cost significantly.
Some people are not aware that the vast majority of consumer/computer chips comes from TSMC Taiwan. Build with huge machines from ASML Netherlands costing up to 400 million USD each. Even Intel lets certain chips produce at TSMC!
Chips shipped to communist China for assembly, making iPhones and millions and millions of cheap mobile phones, motherboards, graphic cards... you name it.
Don't even think what happens if these two companies are sabotaged/attacked.
